GIERNGER QLAJL /QhQL/ Attorneys son PICK-UP MACHINE This invention relates to a sod pickup machine, and'more particularly to a machine for picking up, rolling and discharging sod which has been precut into desired lengths in the field.
The machine of the invention includes novel sod handling and transfer means, as well as a unique motive power mounting system.
DESCRIPTION OF THE DRAWINGS The accompanying drawings illustrate the best mode presently contemplated by the inventors for carrying out the invention.
In the drawings: FIG. 1 -is a side elevation of a device constructed in ac- I cordance with the invention, with parts broken away;
DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in the drawings, the sod pickup or harvesting machine comprises a main frame 1 having a generally rectangular rear portion 2. The parallel frame side rails extend forwardly from portion 2 and incline downwardly, as at 3, to form a support for a first inclined endless belt conveyor 4 which extends longitudinally and is fixed relative to frame 1. A secondary frame portion comprising a pair of spaced transverse rails 5 is secured to the forward ends of longitudinal rail portions 3. Rails 5 extend between portions 3 and include portions 6 and 7 which extend on either side of the secondary frame. As
shown, portions 6 are relatively short while portions 7 are substantially longer than portions 6.
The secondary frame is adapted to mount a floating pickup device for lengths of sod 8 which has been precut in the field. For this purpose a pair of bearings 9 are mounted below the forwardmost rail 5 on rails 3 and pivotally support the rearward ends of a longitudinal conveyor frame 10. Frame 10 suitably mounts a second normally downwardly inclined endless belt conveyor 12 which pivots therewith. A transverse ground-engaging support roller 13 extends between the forward ends of frame 10, and the rear end of a sod pickup plate or tongue 14 is pivotally mounted to frame 10, as at 15, just above roller 13. In addition, a rollable sod holddown wheel 16 is mounted on a horizontal axis at the forward end of an arm 17, above conveyor 12. The rearward end of arm 17 is pivotally mounted to the forwardmost frame rail 5, as at 18. Gravity biases wheel 16 downwardly to hold sod in place on conveyor 12.
Sod 8 which passes up the floating assembly is transferred to fixed conveyor 4 for forming into a sod roll 19. For this purpose, a longitudinal hanging conveyor assembly is mounted directly over conveyor 4 for cooperation therewith. This assembly comprises a frame 20 which is pivotally mounted at its rear end, as at 21 to supports 22 on main frame portions 3; and includes a third belt conveyor 23 thereon. The forward end of the assembly is normally resiliently supported against the force of gravity by a pair of flexible connectors comprising a length of spring 24 attached to the front end portion of frame 20 and a length of chain 25 between the spring 24 and an upstanding brace 26 mounted rearwardly on frame member 3.
The rear end portions of conveyors 4 and 23 converge, and the facing surfaces thereof are driven in opposite directions so that the upper end of a piece of sod 8 will be engaged by both conveyors, causing the sod to be rolled, with gradual downward movement. As this occurs, the sod rolls 19 will gradually lift conveyor 23 from a normally generally horizontal position to an upwardly inclined position;
The sod roll thus formed, and moving downward toward the front of the machine, is now ready for conveying for final discharge. For this purpose, transverse frame rails 5 support a fourth endless belt'conveyor 27 which surrounds conveyor 4 and which is drivable in either direction for discharge on either side of the machine. Conveyor 27' forms a transverse channel having an upstanding rear curb wall 28 and an upstanding front rub rail 29 which is substantially higher than wall 28. Rail 29 is mounted for fore and aft adjustment on a support 30, as by bolts 31 and slots 32, to vary the widthof the channel according to the diameter of the completed roll 19.
A fixed separator plate 33 extends rearwardly from the top of curb wall 28 to slightly above conveyor 4, forming a space 34. Plate ,33 permits a completed sod roll to roll downwardly thereover from conveyor 4 to conveyor 27, while permitting a new piece of flat sod to move up through space 34.
In addition, means are provided to wedgingly receive a sod roll as it moves forwardly-and downwardly onto conveyor 27 and to'retain the flap end of the roll. For this purpose, an upstanding plate or guard 35 having a rearwardly curved upper end portion is mounted on rub rail 29 and above conveyor 27.
Guard 35 is vertically adjustable on rail 29 to accommodate sod rolls of different diameters.
Since it is desirable for the sod roll to reach guard 35 with the flap end up, and since this depends on the point of commencement of sod rolling, this point is made adjustable by raising or lowering the normal hung position of hanging conveyor 23. For this purpose, braces 26 are provided with notches 36 wherein selected links of chains 25 may be locked.
After a sod roll 19 moves onto conveyor 27 and into engagement with guard 35, it moves down the conveyor, w'hile confined between wall 28 and rail 29, until it is discharged therefrom. v
The drive mechanism for the various conveyors is preferably self-contained, and may include a small gasoline powered motor 37 on frame portion 2, which in turn drives a similarly mounted hydraulic pump 38.
Pump 38 is connected through suitable hydraulic lines to a plurality of hydraulic motors 39 which are mounted on the various conveyors to drive them.
The entire mechanism is supported on a tandem wheel system. As shown, a wheel arm 40 is pivotally mounted at its center, as at 41, to frame rails 5, and closely adjacent conveyor 12. Arm 40 extends fore and aft of frame rails 5 and is provided at each end with a wheel 42 which can swivel in all directions. A similar arm 43 and wheels 44 are pivotally mounted as at 41 adjacent the outer end portion 7 of frame rails 5. Arms 40 and 43 can pivot in a vertical plane, with wheels 42 and 44 being independently swivelable, thus providing a substantial flexibility for driving and turning. In addition, a single swivelable wheel 45 is mounted beneath frame 2 for rear support.
In accordance with the invention, a separate power motive means for driving the machine across the field is contemplated, with the machine being floatingly connected thereto. This power means may comprise a small tractor 46 or other similar unit which is small enough to fit behind conveyor 27 and between wheel arm 43 and conveyor 4. Tractor 46 is provided with a suitable frame at its front and rear for connection to the sod pickup machine.
The forward tractor frame portion includes a pair of spaced longitudinal rails 47 having a pair of centrally positioned transversely spaced upstanding pusher bars 48 thereon. In addition, a connector plate 49 extends between the forward ends of rails 47. A pair of transversely spaced beams 50 extend downwardly from forwardmost frame rail 5.
When tractor 46 is in driving position, pusher bars 48 will be A further front connector means is provided which absorbs shocks due to relative vertical movement between the pickup machine and tractor and which tends to overcome any upward lifting forces on the front end of the tractor. For this purpose, an upper L-shaped bracket 51 is secured to portion 31 of frame 5, with an opening 52 in the horizontal bracket lug. A spring support rod 53 extends through opening 52 and is hung from bracket as by a threaded nut 54. The lower end of rod 53 extends through an opening 55 in a lower L-shaped bracket 56, which ishung from rod 53, as by a threaded nut 57. Bracket 56 also includes openings which mate with openings in connector plate 49 and bolts 58 extend through the openings to connect the units together. Brackets 51 and 56 are so positioned that a vertical spring 59 on rod 53 which extends between the brackets provides the shock-absorbing function.
The above-described connector also permits relative tilting or pivoting on a longitudinal axis between the pickup unit and tractor.
ln addition, a rear connector is provided and comprises a lateral extension 60 of rear frame 2, a rear tractor frame portion 61 and a fixed pivotal connection therebetween, as by bolt 62. This structure also permits the relative tilting or pivoting on a longitudinal axis. Furthermore, frame portion 61 engages extension 60 to push the pickup machine rearwardly when desired.
The front and rear connectors permit relative vertical float ing movement of the front of the combined unit, while preventing such movement at the rear. The weight of the combined unit is distributed over the five pickup device wheels and the tractor wheels to thereby permit the unit to be drawn either on or off the sod during pick up without damaging the sod.
In addition, by mounting tandem wheel arms 40 and 43 for The machine of the invention has been found to be very versatile. It not only is easy to handle, but permits sod pick up right to the end ofa row.
